TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

"Be it known that. we, ALVIN CoLnUnN, of Lynn, of the county of Essex, and ELimIDG'E G. STANLEY, of Fitchburg, of the county of Worcester, and State of Massachusetts, have invented an Improved Mechanism for j v Connecting a' Horse with a Carriarfe, and dohereby declare the same toghe fully described in the following D specification, and represented in the-accompanying drawings, of which-` Figure 1 is a top view, i

Figure 2 a front elevation,

Figure 3 a longitudinal section, and

Figure 4 a transverse section of it.

On the 18th dayof Mareh,A. D. 1862, -Letters Patent, uumbered`34,671, were granted to one of us, viz, the said ALVIN COLnURN,for an improved means of attaching a horse to -a vehicle and detaehing him therefrom.

Thel present invention is ani improvement with reference to thatsopatentcd, and is intended to accomplish like results, as we ll as others not incident to such patented invention, theco'nstructionof which, as represented in the patent, rendered it applicable only to the end of`a carriage-shaft. *This limited its use, as it required the shaft to he formed or reduced, so as to receive and hold the ferrul'e of the attachment. p

Our present improvement enables the caseior ferrule,fas it may be termed, to-be applied to the side instead of being slipped on and' around the end part of the shaft, it being x'efdto the shaft either by screws going through it, and being screwed into the shaft, or by a clamp to go around the shaft. i

The drawings show the mechanism in part, as applied to the upper surface or side of a shaft, a portion of which is shown at A.

In such drawings, B denotes a hollow ease, made to straddle and rest onrthe shaft, and provided with per forated ears or projections a a b, to receive fastening-screws to lgo into the shaft. A bar, C, slides into the forward ebd of the case B, and at its front is bent at right angles, and provided with o. `round head, c, through which a hole or eye, d, is made. A helical spring,'D, cneireles that par-t of theV bar which is within the case, and at its rear end bears against a nut,or head,j, fixed on the bar. At its front end .the spriugabuts against4 o/partition, g, extending across the case. The head c ofthe bar VC is intended to enter 'a socketed piece, E, provided with a spring-bolt, F. This bolt is arranged to play vertically through the socket tof the said'scketpiece,`and to go through the'eyed, when in the socket. The head of the bolt is open, or formed with :xn-eye, as shown at t', by which a line or chain may be attached to the bolt. The said socket-piece has three'connectioneyes, le l m, extending from it in manner and formed as shown in the drawings. It also has an arm, n, projecting upward from its bolt-case O, and terminating in an eye-piece, F', provided with two slots or openings,-p qand a tooth or tongue, r, such tongue being-extended from the part s, by which the two slotsp g are separated from cach other. The double eye-piece F, with its tooth, r, and two slots, constitutes a device by which the holt` ease aud socket-piece may be connected with a strap extending down from the saddle of the harness of a horse. For this purpose the strap may be passed through the upper slot, and next down through the lower slot, so as i to cause` the tooth or tongue to enter a hole in the strap, as the tongue of a buckle enters its strap-hole. -The girt,'and breast and back-straps of theharness are to be buckled to the'eonnection-cycs lm, and thus the socket-piece, with its spring-bol t, will be connected with thc harness or the horse by means of the latter. The

lneleading from the bolt is t o pass upward to the saddle, and may be led through one of the rein-guides thereof, ,I

andthenc to the dasher ofthe vehicle. It is intended for each shaft to have applied to it a separate apparatus of the kind described. a i

In order to detach the horse from the carriage, it will -only be necessary to pull on the bo1t-1ines, so as to p draw the bolts out of the heads of the bars B. When the animal is in engagement with the shafts,and drawing the, carriage along, his power of draught will be `exerted against the springs on the hars C, and these willsorve to relieve him and the carriage from the unpleasant effects which sudden forward movements ofthe horse would otherwise produce. We have contemplated the employment of the tug with the bar C, its spring and case, when applied to the side of the shaft, in which case we hook the tug on the bar, made so as to enable the tug to be drawn oli' it by the horse, and we have a pin or holt to go through the part whichreceives the tug, such pin being to hold the tug in such part that it may be necessary to relieve thc horse. By pulling out the pin or bolt, the tug canvbc drown off the bnr by the horse.

We do not herein claim the meehztnism described in the patent hcrcinboforc referred to, but

What We do claim as our improwiement is as foliows:

We claim the arrangement offtlie connection-harms@ B with its bur C, and spring against the side instead of on the end of the shaft, the same rendering no reduction of the shaft necessary in the application of the invention thereto.

v We also claim the combination and arrangement of the spring-bolt with the sookiet-piecc and the bar C, its case and spring, arranged with the shaft as Aset forth.

W Wealso claim the combination of tho double oye-piece F', having a tooth, as deseribed, with the spring-bolt, its case and socket-piece, to bo used with the slide-bnr C, made and applied, or t'o be applied to a. shaft,-sub

stantiztlly as described.

E. e. STANLEY.
